15 Claims. (Cl. 123-451) My invention relates to internal combustion engines and has particular utility in reference to such engines of the general class known as sleeve valve engines as distinguished from poppet valve engines.

Engines of the class referred to are usually provided with a sleeve pocket generally formed between the cylinder and a re-entrant portion of the cylinder head, one or more sleeves operating within said pocket. Difficulties have been experienced in properly maintaining the sleeve pocket free from deposits or sludge which appear in t -e form of carbon, rust, and other accumulations.

It is an object of my invention to provide improved and simplified means for maintaining the sleeve pocket free from accumulations.

A further object of my invention resides in the provision of a series of conduits or passages between the'usual fuel mixture conducting system 0 for the engine cylinder and the sleeve pocket preferably self contained within the engine structure whereby the sleeve valve means will exert a pumping action on the fuel mixture to circulate the same to keep the sleeve pocket washed and 5 free of deposits. Thus the fuel mixture is circulated between the sleeve pocket and the fuel mixture conducting system'carrying from the sleeve pocket any foreign particles, the latter passing to the engine combustion chamber where they are relatively harmless to the engine.

A further important feature of my invention resides in the provision of a novel construction wherein the sleeve valve or valve of the various cylinders of the engine have their upper portions adapted to overtravel the upper face of the cylin-,

derblocl: bounding the cylinders whereby removal of the deposits is facilitated, the deposits being pushed or scraped away from the sleeve pocket.

Other objects and advantages of my invention will be apparent as this specificationprogresses, reference being made, for illustrating the salient features of one embodiment thereof, to the accompanying drawing in which:

Figure 1 is a sectional elevation view through one of the engine cylinders,

Figure 2 is a plan sectional view along the line 2-2 of Figure 1, and

Figure 3 is a detail sectional view along the line 33 of Figure 1.

In the drawing I have illustrated my invention in connection with engine A ofthe Burt-M0001- lum type wherein a single sleeve 10 associated with cylinder 11 contained in cylinder block struc- 55 ture 12 is given the customary combined reciproeating and oscillating movement for accomplishing the well known cyclical events of the engine. The particular type of sleeve movement as well as the number of sleeves employed per cylinder and other general details form no part of my inven tion in themselves, my invention being readily the usual carburetor (not shown) by way of any suitable fuel mixture conducting means such as intake manifold 18 and cylinder block intake passage 19.

The cylinder block structure 12 has an upper face 20 seating a water jacket cover 21 and the face 24 of a flange 22 of the cylinder head structure 23. A depending portion 24'of the cylinder head is spaced from and within cylinder 11 to provide the sleeve pocket 25 the latter being sealed-from combustion chamber 26 by rings 27.

The flange 22 is provided with a conduit or passage 28 in one portion of its under face, this passage extending at one end into the annular recess 29 above the faces 20, 24 adapted to periodically receive the upper portions of the sleeve 10, the recess 29 also being preferably relieved at 30 inwardly of the sleeve.

The cylinder block 12 has a passage 31 opening upwardly at 32 in face 20 and into passage 28 and opening downwardly at 33 into passage 19.

The upper end'34 of sleeve 10 is preferably bevelled downwardly and inwardly to facilitate scraping deposits from thewalls of the cylinder 11.

In operation the movement of sleeve 10 in pocket/25 produces a pumpingaction on the fuel mixture through passages 19, 31, 28 and recess 29, whereby deposits will be continuously removed from the pocket 25 and thence to the passage 19 and combustion chamber 26 as hereinbefore stated. The bevelled edge 34 forms a scraping edge for the cylinder walls facilitating removal of deposits therefrom and the overtravel of the sleeve will force or push the deposits free of the cylinder walls for passage through passage 28.
